NONESafety Requirements
NONEProcedure
Refer to Figure.
Use light pressure to prevent any risk of overheating material.
Any polish marks must be made in a radial direction from root to tip of blade.
Surface finish of the repair area must be the same as the adjacent area.

CAUTION
WHEELS, STONES AND ABRASIVE PAPERS USED TO DRESS, MAKE SMOOTH, OR POLISH A TITANIUM COMPONENT MUST BE OF THE SILICON CARBIDE TYPE.ALUMINUM OXIDE TYPES MUST NOT BE USED.THE MATERIAL WILL OXIDIZE AND CRACK IF MECHANICAL CUTTERS ARE USED HEAVILY. THIS HAS OCCURRED IF THE COMPONENT SHOWS DARK STRAW TO BLUE DISCOLORATION.IF AT ANY TIME THIS COLORATION OCCURS, THE BLADE MUST BE REJECTED.Scallop, make smooth and/or hand polish to remove nicks, scratches and/or damage.
Remove the minimum amount of material necessary to give correct radius.
Refer to the SPM TASK 70-35-03-300-501.
Hand polish the Blade leading and/or trailing edge radius and the vane profile to make a smooth shape.
SUBTASK 72-32-82-350-051 Remove the Damage from the LPC Stage 1.5 Blade
Follow inspection procedure as given in TASK 72-32-82-200-003-A00 (INSPECTION-003, CONFIG-001, CONFIG-002).
Do a visual and dimensional examine on the blade.
SUBTASK 72-32-82-220-051 Examine the LPC Stage 1.5 Blade
Refer to the SPM TASK 70-23-03-230-501.
Make sure there are no cracks in the repaired area.
Fluorescent penetrant examine the repaired area.
SUBTASK 72-32-82-230-051 Examine the LPC Stage 1.5 Blade for Cracks
Refer to Figure.
Apply CoMat 02-003 ADHESIVE TAPE BLACK WATERPROOF to the area which is not to be glass peened.
Apply the adhesive tape.
Use IAE 3J12701 Glass peening fixture 1 off and IAE 3J12702 Glass peening fixture 1 off.
